| |
Linus,
Please pull the latest perf/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2021-02-17
# HEAD: 8bcfdd7cad3dffdd340f9a79098cbf331eb2cd53 Merge branch 'perf/kprobes' into perf/core, to pick up finished branch
The performance event updates for v5.12 are:
- Add CPU-PMU support for Intel Sapphire Rapids CPUs
- Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter sampling event feedback. Not used yet, but is intended for Golden Cove CPU-PMU, which can provide both the instruction latency and the cache latency information for memory profiling events.
- Remove experimental, default-disabled perfmon-v4 counter_freezing support that could only be enabled via a boot option. The hardware is hopelessly broken, we'd like to make sure nobody starts relying on this, as it would only end in tears.
- Fix energy/power events on Intel SPR platforms
- Simplify the uprobes resume_execution() logic
- Misc smaller fixes.
Thanks,
Ingo

Kan Liang (5): perf/core: Add PERF_SAMPLE_WEIGHT_STRUCT perf/x86/intel: Factor out intel_update_topdown_event() perf/x86/intel: Filter unsupported Topdown metrics event perf/x86/intel: Add perf core PMU support for Sapphire Rapids perf/x86/intel: Support CPUID 10.ECX to disable fixed counters
Like Xu (1): x86/perf: Use static_call for x86_pmu.guest_get_msrs
Masami Hiramatsu (1): x86/kprobes: Do not decode opcode in resume_execution()
Peter Zijlstra (1): perf/intel: Remove Perfmon-v4 counter_freezing support
Steve Wahl (2): perf/x86/intel/uncore: Store the logical die id instead of the physical die id. perf/x86/intel/uncore: With > 8 nodes, get pci bus die id from NUMA info
Zhang Rui (3): perf/x86/rapl: Add msr mask support perf/x86/rapl: Only check lower 32bits for RAPL energy counters perf/x86/rapl: Fix psys-energy event on Intel SPR platform
